ELECTRIC HEATER.

Application led April 10, 1925. Serial No. 22,073.

To all whom 'it may concern Be it known that I, MICHELLE S. GA- ZELLE, asubject of the King of England (who has declared his intention ofbecoming a citizen of the United States), residing at Highland Park, inthe county of Wayne and State of Michigan, have invented a new anduseful Improvement in an Electric Heater, of which the following is aspecification.

My invention relates to a new and useful improvement in an electricinstantaneous heater, and has for its object, the provision of a waterheater of this class which will be durable in structure, economical ofmanlifacture and highly eicient in use.

Another object of the invention is the provision of a water heater ofthis class, which will be compact and aiord a maximum of heating servicefor the iowing water.

Another object of the invention is the provision of a water heater ofthis class in which the fiowing water is directed through variouspassages, so arranged that the cooler water is heated to some extent bythe water which has been raised to a higher temperature on account ofthe close relation of the various passages in which the water fiows.

Another object of the present invention is the provision of an electricwater heater having control means, automatically operated upon theturning on of the water, so that the hetin of the water beginsimmediately. with t eV` iowing of the water through the heater. Y

Another object of the invention is the provision of a water heater ofthis class, made from a plurality of tubes mounted in separate rings, sothat the device may be quickly and. easlly taken apart for cleaning orrepairing, the various arts being of a standard size and adapted formounting in cooperatit'e relation.

Other objects willappear hereinafter.

The invention consists in the combination and arrangement of partshereinafter described and claimed.Y

The invention will be best Vunderstood from a; reference to theaccompanyin drawings w'liich forma partj of this speci cation andinvwlch 1 is 'a central, vertical, sectional view OfFtlhe invefonz. l d1 l, 2 isa ya `entary,en argel sectiona vieitgf the Fig. 3 is a sideelevational view of the invention.

Fig. 1- is a longitudinal central sectional view ot' the faucetattaching means.

Fig. 5 is a central sectional view of a modified i'orni ot' attachingmeans.

The invention, as shown in the drawings, comprises an outer casinghaving a base T. mounted upon which yis a housing 8 having a cover 9attached thereto and provided with al centrally disposed opening havinga flanged neck 10. The housing is insulated with a layer of asbestos 11.Mounted in the housing, which is preferably of cylindrical form,extending diametrically thereof is a supporting wall 12, upon which ismounted a cylinder forming housing 13, in which is slidably positioned apiston head 14C iXcdly mounted upon the piston rod or stem 15. A collar16 is mounted on the stem 15, exterior ot' the housing 13. Positionedupon the stem in embracing relation, so as to engage, at one end, thecollar 16, is a spiral spring 17, the other end ot which engages theangle block 18 through which the-rod 15 is pro jected. The rod 15carries, at its outer end, a contact 1%) adapted, upon movementsutilciently in one direction, to close the knife blade switch 2t),which is 'electrically connected to the socket plug 21 adapted forreceiving the plug 22, which is connected to a suitable source ofelectrical energy. One ot the contactsI of the kniie switch is connectedto the socket plug 21, and the other contact is connected to an electricheating element described later. An inlet pipe 23 communicates with thelinterior of the cylinder forming housing 13. The pipe 23 is adapted forconnection with a supply of water, such as, the ordinary city supply, bymeans of a pipe, or hose, 25. The hose 25 is connected to a nipple 27,which has an enlargement 26 formed thereon, adjacent one end. The otherend of the nipple 27 is restricted. as at 28, and is provided with aperipheral fiange 30. A packing nut 31 is adapted for threading on theneck 32 4of the globe-shaped attachment 33, which is threaded exteriorlyand interiorly, at its upper end. Packing 29 is positioned between thebase of the packing nut 31 and the flange 30, so as to secure a watertight swivel connection. If the faucet to which the pipe 25 is to beconnected is exteriorly threaded, the globeshaped member 33 may bethreaded to the faucet using the interior threads. When, however, thefaucet is not threaded, as shown by 37, a rubber plug 35 is used forembracing the faucet 37 and the annular interiorly threaded member 34 mabe threaded upon the exterior threads o the globe-shaped member 33. Setscrews 36 projected through the member 34 will serve to press the rubberring or plug 35 into close engagement with the faucet 37, to provide awater-tight connection. When the connection is made to the faucet andthe water turned through the pipe 23 into the cylinder-forming housing13, the piston head 14 causes the rod 15 to move, so as to close theknife blade switch 20 through the contact 19. The water then will flowthrough the pipe 38, which is connected to suitable piping, and threadedinto an openin formed in the ring 39, a control valve 24 beinginterposed in the pipe 38. These rings are preferably made from metal,as are also the various tubes used. The ring 39 is positioned upon aring 41, and has a cut-away portion 40 to provide a passage for thewater flowing through the pipe 38. Mounted at one end in the ring 39 ina. press t is a tube 42, the cut-away portion 40 serving to conduct thewater into the interior of the tube 42. Pressed into a recess 45. formedin the ring 41, in a press tit, is one .end of a tube 45, which isprovided, at its upper end. on its circumference, with a plurality ofopenings 46, so that the water flowing upwardly within the tube 42 ispermitted to pass through the openings 46 into 'the interior of the tube45.

The upper end of the tube 42 is pressed into a recess 45 formed in thering 43. and the upper end of the tube 45 is pressed into a cut-awayportion of the ring 43, the connections of these various tubes with therings in which they are pressed being a water-tight connection. Thewater flowing downwardly within the tube 45 is then permitted to passthrough an opening 48 formed in a ring 41. The opening 48 is incommunication with a. passage 49 formed with the ring 50 and the ring4I, which has a cut-away portion 51 to permit the passage of the water,so as to; flow upwardly, interiorly of the tube 54 and exteriorly Vofthe tube 53. The tube 54 4is pressed into the ring 41 and the tube 53 ispressed into a recess formed in the ring 50 at the lower ends of saidtubes. The upper end rof the tube 54 is pressed into a cut-away'portionof the ring 57 and the upper end of the tube 53 is pressed into acutaway portion of the ring 58 and the ring 57. `The up er end of thetubev53 is provdedfwitb a p uraltyof openings. 59 which permit thepaesageof thewaterinto the interior of the tube y.53, so as topermit'its flowing downwardly exteriorly of the tube 60, the tube 60being pressed jinto the ring 58 .at its upper end and projecting beyondthe same. The i lower end of the tube 60de pressed into a"A recessformed in the 50, the tube 60de' being provided, at its lower end, witha plurality of openings 63, tyo` 'permit the pas-ff?v sage of thewwaterwl'cifis exterior of thef tubeO to the interior thereof. The uppel"v endofythe tube 60 is interiorly three for the rece tionof a T 65. Mountedinl. one end of tlge T is a tube 66 which'Sup-" ports a housing67 havinga `:face dial mount?.l`

The plates are Vjoined together at the bottom and the top by suitablebolts 75, the pairs of plates at opposite ends of the tubes being heldtogether by rods 76. If it is desired to disasselnble the invention forcleaning the various tubes, the pipe 23 may be unscrewed from connectionwith the housing 13, the cover 9 removed, and the various tubesdisconnected upon disconnecting the plates connected thereto. If desiredthe rings may be provided with gaskets 81 and 82 to form a tighterconnection than would be the case were the metal to be pushed together,Without gaskets.

Ihile I have illustrated and described the preferred forni of structure,I do not Wish to limit myself to the precise form of structure shown,but desire to avail myself of such variations and modifications as comeWith in the scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
